MEANS FOR VENTILATING GRAINJ 84C.

SPECIFICATION forming part of Letters Patent No. 269,135, datedDecember 12, 1882. l `Application tiled March 7, 1882. (No model.)

which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention has for its object toproduce a simple, inexpensive, and eficient means of ventilation for wheat-bins, granaries, storehouses, railway freightcars, lholds of vessels, boxes, barrels, and other receptacles Where grain, fruits, vegetables, and other perishablev articles are temporarily storedV or conveyed from one place to another.

In the drawings, Figure 1 is a longitudinal sectional view of a granary or store-house to which my invention has been applied; Fig. 2, a transverse sectional view of the same; Fig. 3, a bottom plan view looking from the under side; Fig. 4, a detail view ot' one of the end caps; and Fig. 5 a modification showing my invention applied to the hull of a vessel.

Referring by letter tothe drawings, A designates the structure, which is mounted upon suitable corner-pieces, B, and provided at its top with a ventilator, C.

D denotes longitudinal slots or openings in the.4 bottom or door of the structure A, which are covered by strips of perforated sheet metal, wire-gauze, or other suitable perforated material, E.

Above the slots D, and at right angles to the same, are arranged transversely one or more series of horizontal perforated tubes, F,

the ends of which rest in openings G, formed in the sides H of structure I designates the end caps, consisting of a base-plate, J, having a central opening, K, and semi-cones L. These caps are secured to the sides of the structure by means of their base-plates J at the openings G, `with their central openings, K, tallying with the ends of tubes F and the semi-cones L above. It will thus be seen that the latter, while they do not obstruct the free passage of the air, shelter the openings G from rain, dust, Src., that would damage the grain or other articles inside. Owing to their cone shape therain-water will readily run oft'.

It is obvious that the perforated tubes may be arranged longitudinally, diagonally, transversely, or in any other manner without departing from the spirit of my invention.

When my invention is applied to freight cars, boxes, &c., the application and arrangement of parts is substantially as herein specified; but when applied to the hull ot' a vessel the slots in the `bottom are ot course omitted, and the openings G and end caps, I, arranged above Water-line in the rail or bulwark of the vessel. The tubes are then curved down through the hold ofthe vessel and up and ont at the other side, and are preferably imperforate until they reach the hold, all as shown in Fig. 5 of the drawings.

In practice the pure air enters at the openings G into the tubes, and from thence escapes through the perforations therein and circnlates through the stored matter. It also enters through the slots in the bottom, and the foul air escapes through the ventilator at the top or through the openings by which it entered. A free circulation of pure fresh air is thus obtained, and thei'ruits, vegetables, grain, 86o., prevented from rotting and preserved in a perfectly-fresh state. By this ineans wheat and other grain is preserved from injury by sweating during t-he drying process.

Having thus described my invention, Iclaim and desire to secure by Letters Patent of the United Statesl. The combination, with the tubes, of the protecting end caps, consisting ot' a base-plate, by which it may be secured to the structure, and provided with a central opening, in which the ends of the tubes are adjusted, and asemicone, as set forth.

2. The combination, with the structure provided With transverse Ventilating-tubes pro jecting on the outside of the structure, of the herein-described protecting-caps, consisting ot' a base-plate provided with a central opening, by Which it is adjusted over the projecting ends ofthe tubes, and with a semi-cone, as set forth.

3. The combination, with the structure hav- 'ICO ing parallel longitudinal slots in its bottom eX- own I have hereto affixed my signature in prestendingits entire length, of the transverse perence of two witnesses. forated tubes arrzm ged at right angles there- 1 to, with their ends projecting through the sides JOHN KENNEDY STREET' 5 and restingin protecting semi-conical caps, as Witnesses:

set forth. ROBERT BLUNKs PAUSTE,

In testimony that Iclaim thelforegoing as my THOMAS DUGELBY.
